To all whom it may concern..-

Be it known that I, RoBE sr S'rooK, a pitizen of the United States, residing at Bu'llalo,

the county of Erie and State of New York, have invented a new and useful Improvement in Bottle-Stoppers, of which the following is a specification.

This invention relates to a bottlestopper which is more particularly designed for seal- 5 ing or closing the necks-of bottles containing beverages, although the same may also i be used forbottles in which other material is packed.

The object of this invention 13 to provide a stopper which is simple and inexpensive in.

construction, which can be readily applied to and removed from the bottle without the use of special tools or machinery, and which will effectually seal the bottle when applied thereto.

in the accompanying drawings, Figure 1 is a fragmentary side View of a bottle-neck having my improved stopper applied thereto. Fig. 2 is a vertical section thereof. 'Fig. 3 is a bottom lan view of the stopper removed from the bottle. Fig. 4 is a side elevation of the cap which forms part of my improved stopper, showing the condition of the same before the stopper is completed. Fig. 5 is a plan view of the split spring-ring whereby the cap of the stopper is yieldinglydield upon the neck of the bottle.

Similar letters of reference indicate corresponding parts throu bout the several views.

The neck A of the ottle which is intended to receive my improved stopper is provided at its up er end or mouth with an external annular ead or enlargement a, forming a downwardly-facing shoulder a on the exterior of the neck.

I My improved stop er comprises a ca B, adapted to fit over tfie neck of the bott e, a disk-shaped packing C, of cork, rubber, or other suitable material, seated on the under side of the cap and adapted to rest upon the upper end of the neck, and a split spring-ring D applied to the rim of the cap and adapted to contract the lower part thereof and hold the same in engagement with the shoulder of the bottle-neck for securing the capfirmly thereto.

In order to render the rim of the bottle more elastic and enable the same to yield to the pressure of the spring-ring, this rim is provided with a plurality of vertical slots 0, extending upwardly from the lower edge of g the rim and forming an annular row of depending elastic fingers or lips E on the rim. The spiit ring is applied to the outer side of 1 these lips, and the ends of the latter are bent or curled outwardly and upwardly around 1 the ring, as shown 1!) Figs. 1 and 2, whereby 1 the ring is permanently connected with the ca anbl spring-ring the internal diameter therei of is less than the external diameter of the head on the bottleneck. Upon pressin the stop or downwardly over the neck 0 the bott e the split ring and the depending lips of the cap are expanded in passing over the after passing below this bea and engagin with the shoulder on the under side thereo are so proportioned that when the lips are held in engagement with the shoulder of the head by the spring-ring the packing of the cap i'its against the u per end of the neck. This shoulder instcac of being abrupt inclines downwardly slightly, which causes the resilience of the s ring in pressing the lips against the SllOlll( er to constantly tend to draw the cap downwardly, and thus insure a perfectly tight closure of the packing over the mouth of the bottle at all times and also compensating for slight inaccuracies in the manufacture of the parts.

The stopper can be removed from the bottle by exerting an upward pull upon the same sufficient to overcome the resilience of the spring and cause the same to spread sufficiently together with the lips of the cap to clear the head of the bottle-neck.

In order to facilitate removal of the stopper from thebottle, one end'of the split ring is provided with a laterally'projecting nose or ifting lug f. Upon pressing upwardly against this lug either by means of the fingers or by means of an ordinarybottle-opener the 1ptopper can be readily. pried off from the nec For preventing injury to the fingers when the stopper is removed without the'aid ofa tool the liftin -lug is constru ted in the form of a loop, as s own in Figs. 3 and 5, whereby only round surfaces are formed with which the fingers engage instead of sharp or angular surfaces, which would be likely to injure the fingers. By permanently connecting the cap and spring-ring of the stopper these parts are not iable to become misplaced [when removed from the bottle. a

head of the bottle-neck and a ain contracted,

The parts of the bottle and of the stopper I in the normal condition of the lips 'loWer ends of said lips are connected and 20 My improved bottle-sto per can be readily replaced over the mout of the bottle, so as to properly seal the same after having been once removed, Without the use of any special tools for this purpose. This renders t e same particularly desirable for bottling, llquids for household use, which require the bottleto be again sealed after the (contents have been partially used.

I claim as my invention- 1. A bottle-sto per comprising a cap having its rim slitte to form an annula royv of depending lips and a spring-ring to which the lower ends of said lips are connected, substantially as set forth. y

2. A bottle-st0pper comprising a cap hav ing its rim slitted to form an annular row of depending lips, and a split ring to Which the which is provided at one end with a laterallyprojecting lug, substantially as set forth depending lips, a split spring-ring around which the lower ends ofsaid lips are curled for connecting said ring With said lips, and

a laterally-projecting lug of loop form arranged on one end of said ring, substantially as set forth.

Witness my hand this 2d day of September, 1905.
